Subfield Codes

$d - Coordinates - westernmost longitude (NR)
$e - Coordinates - easternmost longitude (NR)
$f - Coordinates - northernmost latitude (NR)
$g - Coordinates - southernmost latitude (NR)
Subfields $d, $e, $f, and $g always appear together. The coordinates may be recorded in the form hdddmmss (hemisphere-degrees-minutes-seconds), however, other forms are also allowed, such as decimal degrees. The subelements are each right justified and unused positions contain zeros.
$j - Declination - northern limit (NR)
$k - Declination - southern limit (NR)
Subfields $j and $k are each eight characters in length and record the declination in the form hdddmmss (hemisphere-degrees-minutes-seconds). The degree, minute and second elements are each right justified and the unused positions contain zeros. (If declination of center is known, it is repeated in both subfields).
$m - Right ascension - eastern limit (NR)
$n - Right ascension - western limit (NR)
Subfields $m and $n are each six characters in length and record the right ascension in the form hhmmss (hour-minute-seconds). The hour, minute and second elements are each right justified and the unused positions contain zeros. (If the right ascension of center is known, it is repeated in both subfields).
$p - Equinox (NR)
Equinox or epoch for a celestial entity. Usually recorded in the form yyyy (year) according to the Gregorian calendar, but may include a decimal including the month in the form yyyy.mm (year-month).
$r - Distance from earth (NR)
Distance of celestial bodies, such as planets or stars, from the Earth in light-years.
$s - G-ring latitude (R)
$t - G-ring longitude (R)
$x - Beginning date (NR)
Beginning of the time frame specific to the coordinates. The date is structured in the form of yyyymmdd. When no date is recorded, it is assumed that the coordinate information is current.
$y - Ending date (NR)
Ending of the time frame specific to the coordinates. The date is structured in the form of yyyymmdd. When no date is recorded, it is assumed that the coordinate information is current.
$z - Name of extraterrestrial body (NR)
Name of a planet or other extraterrestrial body specified when the coordinate data recorded in subfields $d, $e, $f and $g do not describe an entity on Earth.
$0 - Authority record control number or standard number (R)
See description of this subfield in Appendix A: Control Subfields.
$2 - Source (NR)
MARC code that identifies the source of the data recorded in field 034. If different sources are recorded, separate fields should be used. Code from: Cartographic Data Source Codes.
$3 - Materials specified (NR)
$6 - Linkage (NR)
See description of this subfield in Appendix A: Control Subfields.
$8 - Field link and sequence number (R)
See description of this subfield in Appendix A: Control Subfields.
